First study to show that when counting frozen as well as fresh embryos, single embryo transfer does not reduce the chances of having a baby
Doctors in Australia have found that transferring one embryo instead of two during an IVF cycle does not reduce the chances of a woman having a baby, when frozen as well as fresh embryos are taken into account. Dr Jim Catt, Embryology director of Sydney IVF, Australia, and his colleagues have conducted the first study looking at cumulative... view more... (2003-06-27)
In-vitro fertilization improved with 3-D/4-D-guided embryo transfer and new placement target
Beverly Hills, Calif. and Washington DC (ASRM Annual Meeting) - October 15, 2007 - The pregnancy rate for patients undergoing in-vitro fertilization (IVF) is improved when doctors use advanced 3D/4D imaging to guide the placement of embryos to the point where the endometrium is most receptive to implantation. view more (2007-10-17)
Nutrition a major factor in rise in twin pregnancies
The commonly held view that IVF is the only culprit in the steady increase in the numbers of twins born over the past thirty years was challenged by a scientist speaking at the 22nd annual conference of the European Society of Human Reproduction and Embryology in Prague, Czech Republic. view more (2006-06-21)
Rise in ICSI cycles suggests infertility could be affecting more men than women
Infertility may be becoming more of a man's problem than a woman's problem according to new figures released at the 21st annual conference of the European Society of Human Reproduction and Embryology. view more (2005-06-22)
Single embryo transfer - a new understanding of factors for success
Berlin, Germany: Transferring a single embryo to a woman can result in a similar number of pregnancies as double embryo transfer, while at the same time reducing the risk of multiple births and the complications due to twin pregnancies, a scientist said today at the 20th annual conference of the European Society of Human Reproduction and... view more...

Mayo Clinic researchers recommend embryo transfer delay for at-risk women
Mayo Clinic researchers have determined a method to achieve the best results for the mother's health and birth of a live baby for women who undergo in vitro fertilization who demonstrate risk of ovarian hyperstimulation syndrome. view more (2006-10-25)
ART laws put patients at risk and should be changed, warns head of Germany's IVF registry
Germany's restrictive legislation on embryo protection is putting women and babies at risk and should be modified, the chairman of the German IVF registry will tell a meeting of international fertility experts. Professor Ricardo Felberbaum will warn participants at the European Society of Human Reproduction and Embryology annual conference that... view more... (2003-06-27)
IVF technique enables pregnancy without multiple births, Stanford researchers find
An in vitro fertilization technique that can avoid multiple births appears to be effective for women older than 35, according to researchers at the Stanford University School of Medicine. view more (2007-10-02)
Single thawed embryo transfer after PGD does not affect pregnancy rates
Transferring just one embryo at a time to a woman's womb after embryos have undergone preimplantation genetic diagnosis (PGD) and freezing at the blastocyst stage has become a real option after researchers achieved pregnancy rates that were as good as those for blastocysts that had not had a cell removed for PGD before freezing. view more (2009-06-30)
Differences between parental selection for adoption and embryo donation unfair
The magnitude of the difference between the selection criteria for adoption and embryo donation is unfair and unjustifiable. The procedures should be reassessed, argues an analysis in the Journal of Medical Ethics. The differences hinge on the social and emotional suitability criteria for adoption - fitness to parent - and the medical suitability... view more... (2002-05-27)
Identifying the metabolism of a healthy embryo could improve infertility treatment
Embryos that are most likely to result in a pregnancy are crucial to the success of in vitro fertilization (IVF) but are difficult to identify. Researchers at Yale School of Medicine, led by Emre Seli, M.D., are developing a fast, non-invasive test to help assess embryo viability for IVF. view more (2009-10-21)
Secrets in a seed: Clues into the evolution of the first flowers
Approximately 120-130 million years ago, one of the most significant events in the history of the Earth occurred: the first flowering plants, or angiosperms, arose. view more (2009-09-15)
Children born after PGD as healthy as those born after conventional IVF treatment
Children born after embryo biopsy for preimplantation genetic diagnosis (PGD) do not show any more major malformations than those born after artificial reproduction technologies (ART) without PGD. view more (2007-06-18)
Scientists discover stage at which an embryonic cell is fated to become a stem cell
Cambridge scientists have discovered the stage at which some of the cells of a fertilised mammalian egg are fated to develop into stem cells and why this occurs. view more (2007-01-11)
Therapeutic Cloning No Longer A Dream, Says Scientist Who Produced First Cloned Embryonic Stem Cell
A member of the team who were the first in the world to produce stem cells from a cloned human embryo told the 20th annual conference of the European Society for Human Reproduction and Embryology on Wednesday 30 June that the work could generate potentially unlimited undifferentiated stem cells. These could eventually be used for tissue repair and... view more... (2004-06-30)
How do you know whether you are male or female?
New research published online this week in the open-access journal PLoS Biology investigates this basic and much-studied question in the fruit fly, and comes to a surprising new conclusion. view more (2007-12-27)
First calves from gene diagnosed embryos born at MTT Agrifood Research Finland
Results from quantitative trait gene mapping (QTL) have been utilised for the first time in the selection of bovine embryos. The genotypes of two genes affecting milk yield and composition have been analysed from pre-implantation embryo biopsies. The first four female calves with known milk production genotypes were recently born at the... view more... (2003-08-14)
Size of a woman's uterus can predict whether she is at risk of having very premature twins after IVF
Using ultrasound to measure the height of a woman's uterus is a good way to predict whether or not she is at risk of having babies born prematurely if she becomes pregnant with twins after IVF. view more (2008-07-09)
IVF Children At Increased Risk Of Neurological Disorders (pp 459, 461)
A Swedish study in this week's issue of THE LANCET suggests that children born after in-vitro fertilisation (IVF) could be at an increased risk of developing neurological problems, especially cerebral palsy. The authors conclude that a reduction in this risk is possible if only one embryo is transferred during IVF, reducing the likelihood of twin... view more... (2002-02-06)
Toothed Embryo Of Mammoth
For the first time, a well-preserved lower jawbone of a mammoth embryo is found by paleontologist E.N. Mashchenko and his colleagues in the Tomsk area. Judging from the size and structure of the bone, the embryo is from 14 to 16 weeks old, which is the last stage of its development (the pregnancy of mammoths as well as elephants lasts for almost... view more...
